The utility model discloses because adopt test platform and water tank as test tool, easy operation is convenient, the watertight door can be hunted leak in the workshop in advance, can shorten the immersed tube tunnel construction time limit for a project greatly, improvement work efficiency.
Description
Technical field
This utility model relates to immersed tube tunnel technical field of construction, especially a kind of immersed tube tunnel watertight door leakage detection apparatus.
Background technology
At present, in immersed tube tunnel is constructed, each docking site of pipeline section is respectively provided with end seal wall, for temporary enclosed, water proof, after treating pipeline section docking, in succession draws water, removes envelope wall.Watertight door is a temporary part of immersed segment, it is made up of steel beam column, it is arranged on the side near water of structure, either it is arranged on the watertight door on concrete end seal wall, also it is mounted in the watertight door on steel construction envelope wall, under construction period, normal applying working condition, require to bear the head pressure of maximum 30m and non-leakage, require that watertight door must carry out workshop water-pressure sealed test (test pressure 0.3MPa after completing, constant voltage time 24 hours), to verify the sealing property of watertight door, it is ensured that do not drip, do not seep water.During immersed tube section floating, sinking, such as there is percolating water situation in watertight door, consequence is hardly imaginable, even affect the service life in tunnel, therefore, watertight door effect on steel end seal door is great, must carry out infiltration detection before use, and whether percolating water is always a technical barrier the most quickly to detect watertight door.
Summary of the invention
The immersed tube tunnel watertight door leakage detection apparatus that the purpose of this utility model is just to provide a kind of simple in construction, easy to operate, work efficiency is high.
Immersed tube tunnel watertight door leakage detection apparatus of the present utility model, including water tank, test platform, increase air pump, it is characterized in that, water tank is made up of bottom panel, top panel and three pieces of side panels, side end opening, opening is formed around connecting plate, and connecting plate has evenly distributed connecting hole, increases air pump and is connected with water tank by valve, connecting tube, water tank top panel；Test platform is by main panel, anyhow beam, handwheel tie system, hinge is constituted, anyhow beam is affixed with main panel inner face, main panel surrounding has the through hole corresponding with connecting hole on water tank connecting plate, on water tank connecting plate, connecting hole is connected with the through hole fastening bolt on main panel, observation port it is provided with on main panel, hinge is arranged on main panel outer face, the fixing channel-section steel of handwheel tie system is arranged on main panel inner face, hands is taken turns, pull bar is fixing on the home panel by fixing channel-section steel, one end of pull bar is connected with handwheel, the other end is that free end passes fixing channel-section steel and main panel.
The operation principle of immersed tube tunnel watertight door leakage detection apparatus of the present utility model is, first the hinge auricle on watertight door is passed through door stud connection with the hinge on test platform main panel outer face, again the pull bar auricle on watertight door is connected with the pull bar free end bearing pin of handwheel tie system, and places sealing rubber strip at watertight door lip.Rotation hand wheel, the sealing lip of watertight door surrounding, sealing rubber strip are fitted tightly by pull bar with test platform main panel outer face.Afterwards, being buckled in by water tank on test platform, test is compressed with round steel with rubber blanket with between platform main panel and water tank connecting plate contact surface, and tightens by fastening bolt and guarantee not permeable leaking.Water filling in water tank, after filling, starts supercharging air pump and pressurizes water tank, and pressure stops pressurization after reaching 0.3MPa, closes valve, keeps constant voltage 24h.By the observation port on main panel, percolating water situation during viewing test.
Immersed tube tunnel watertight door leakage detection apparatus simple in construction of the present utility model, owing to using test platform and water tank as test instrument, simple and convenient, watertight door can shift to an earlier date hunts leak in workshop, is substantially shorter the immersed tube tunnel construction period, improves work efficiency.
